How Much Basic Personal Amount Can I Claim In My Tax Return?
The calculation primarily depends on your net income and your tax residence. If you are a Canadian tax resident for the full year, you are entitled to claim the full Federal and Ontario Basic Personal Amount when filing your income tax. For 2022, the full Federal Basic Personal Amount is $14,398 and the full Ontario Basic Personal Amount is $11,141.
What Is The 90% Rule?
The 90% rule applies to taxpayers who have not been a Canadian tax resident for an entire year, whether they are departing from or arriving at Canada. As a result, they may only be entitled to the full Basic Personal Amount deduction if 90% of their net worldwide income is Canadian-sourced. Otherwise, their entitled amount will be prorated based on the length of their tax residence in Canada.
